NHTSA Complaint #10369425 — 2003 CHEVROLET TRAILBLAZER

SPEEDOMETER ON OUR 2003 CHEVROLET TRAILBLAZER STARTED ACTING ERRATICALLY--NEVER GOING DOWN TO ZERO, GOING UP TO 80 OR ABOVE FOR NO REASON, ETC.--ABOUT 2 YEARS AGO. IN A MATTER OF WEEKS, AFTER THE FIRST ONSET OF THE PROBLEM, IT STOPPED WORKING ALTOGETHER AND HAS NOT MOVED ABOVE ZERO SINCE. WE WERE TOLD THAT THE WHOLE INSTRUMENT CLUSTER WOULD HAVE TO BE REPLACED TO FIX THE ISSUE WITH THE SPEEDOMETER. LUCKILY, ALL OF THE OTHER GAUGES ARE STILL FUNCTIONING PROPERLY AS OF RIGHT NOW BUT FROM WHAT I HAVE FOUND IN MY RESEARCH OF THIS ISSUE IT SEEMS TO BE ONLY A MATTER OF TIME BEFORE THEY ALL WILL CEASE TO FUNCTION PROPERLY AS WELL. I HAVE SEEN AND READ MANY REPORTS ABOUT THIS PROBLEM BUT I AM SURE IT WOULD BE SAFE TO SAY THAT THERE ARE MANY MORE INSTANCES THAT HAVE GONE UNREPORTED. PLEASE LOOK INTO THIS VERY SERIOUS SAFETY ISSUE AS SOON AS POSSIBLE. IT DOES NOT SEEM LIKELY OR MERELY COINCIDENTAL THAT SO MANY TRAILBLAZERS ARE EXPERIENCING THE VERY SAME INSTRUMENT CLUSTER FAILURE. *TR
